The current series mainly adds the support for booting the DSPs from the Linux kernel. This series forms the foundation for adding support for a new 64-bit DSP (C71x DSP) to be posted in a separate series. Support for attaching to pre-booted DSPs (from bootloader) will be done in a future series. The C66x DSPs can boot either using firmware segments loaded into either DDR and/or internal DSP RAMs. IPC is through the virtio-rpmsg transport. There is no Error Recovery or Power Management support at present. The driver also does not support loading into on-chip SRAMs at present. The patches are based on the current rproc-next branch, and does use couple of patches posted earlier from the OMAP remoteproc series [1] and TI K3 R5F series [2]. It also leverages the fixed memory carveout fixes series [3]. Following is the patch summary: - Patch 1 adds the bindings in the YAML format. - Patch 2 adds the basic remoteproc driver for the C66x DSPs - Patch 3 is an enhancement to support loading into the DSP's internal RAMs directly. regards Suman [1] https://patchwork.kernel.org/patch/11455135/ [2] https://patchwork.kernel.org/patch/11456383/ [3] https://patchwork.kernel.org/cover/11447649/ Suman Anna (3): dt-bindings: remoteproc: Add bindings for C66x DSPs on TI K3 SoCs remoteproc/k3-dsp: Add a remoteproc driver of K3 C66x DSPs remoteproc/k3-dsp: Add support for L2RAM loading on C66x DSPs .../bindings/remoteproc/ti,k3-dsp-rproc.yaml | 180 ++++ drivers/remoteproc/Kconfig | 16 + drivers/remoteproc/Makefile | 1 + drivers/remoteproc/ti_k3_dsp_remoteproc.c | 818 ++++++++++++++++++ 4 files changed, 1015 insertions(+) create mode 100644 Documentation/devicetree/bindings/remoteproc/ti,k3-dsp-rproc.yaml create mode 100644 drivers/remoteproc/ti_k3_dsp_remoteproc.c -- 2.23.0
